Egg Bench by Grace Chen

Grace:

I made my furniture debut with a conceptual piece that blurs the line between art and design. Composed of six dozen eggs delicately seated on a solid walnut base, Egg Bench was created to challenge common misconception that eggs are fragile. By researching this complex
physical structure, I discovered that each egg can support and distribute a load of 120 lbs maximum. To insure success, my unique design isolates each egg into an optimum position and ensures that it remains motionless. The result is a piece that invites the sitter to suspend their disbelief and to embrace a new appreciation for this powerful, natural creation.
